I can't print via wireless network from my MacBook Pro to my Epson CX4450 printer. The printer is ,connected to a Windows XP machine with printer sharing turned on, via USB port. If I connect the MacBook directly to the printer via the USB cable, it prints fine. But not via wireless network. I see the printer from the MacBook, and print jobs go to it. However they all stop without printing. I have been to the Epon web and installed the latest driver for my OS X MacBook. Is there some SPECIAL driver I need to print via wireless network? Can anyone offer any other help? Thanks! -Allen McCarley
